[0017] The present invention is further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the scope of protection of the present invention.

[0018] See also Figures 1 to 4The utility model relates to a rivet pressing device, including a base 1, a frame 7, a workpiece positioning assembly and a pressing assembly. The frame 7 and the workpiece positioning assembly are installed on the base 1, the frame 7 spans the workpiece positioning assembly, and a pressing assembly corresponding to the workpiece positioning assembly is installed on the frame 7. The pressing assembly includes a pressing cylinder 9, a pressing lifting plate 10 and a pressing pipe 5. The pressing cylinder 9 is arranged in a vertical direction and is installed on the frame 7. The pressing lifting plate 10 is slidably installed on the frame 7 and is driven by the pressing cylinder 9; the pressing pipe 5 is installed on the pressing lifting plate 10 and rises and falls with the pressing lifting plate 10; the pressing pipe 5 is connected to a vacuum pump.

[0019] In this embodiment, the combination of the base 1, the frame 7 and the workpiece positioning assembly provides a solid foundation and stable support, thereby helping to ensure accurate positioning and stability during the pressing process.

[0020] Through the coordinated action of the vertically arranged pressing cylinder 9 and the pressing lifting plate 10, precise control of the pressing process can be achieved, thereby ensuring the pressing force and the accuracy of the pressing process.

[0021] The connection design between the pressing tube 5 and the pressing lifting plate 10 enables the pressing tube to rise and fall with the movement of the lifting plate, thereby effectively transmitting the pressing force and ensuring the uniformity and stability of the pressing. At the same time, the pressing tube 5 is also connected to a vacuum pump to adsorb the rivet.

[0022] The workpiece positioning assembly includes a positioning plate 2, a workpiece mounting seat 4 and a guide sleeve 3. The workpiece mounting seat 4 is installed in the middle of the positioning plate 2. The workpiece mounting seat 4 is provided with a workpiece placement groove. Two guide sleeves 3 are installed on the positioning plate 2 and are symmetrically arranged along the positioning plate 2. Through the combination of the positioning plate 2, the workpiece mounting seat 4 and the guide sleeve 3, accurate positioning of the workpiece can be achieved.

[0023] The workpiece mounting seat 4 provides a workpiece placement groove, which helps to ensure the correct installation and positioning of the workpiece. The workpiece placement groove is set in the workpiece mounting seat 4, which facilitates the placement and removal of the workpiece, making the operation simpler and more efficient. The middle part of the workpiece mounting seat 4 is installed on the positioning plate 2, combined with the symmetrical arrangement of the guide sleeve 3, which helps to enhance the stability of the workpiece during the pressing process and reduces the possibility of movement or offset of the workpiece.
